Title Candidates for low-luminosity supersoft sources in the Magellanic Clouds

Author Dr Frank Haberl
Description We propose XMM-Newton observations of new candidate supersoft X-ray sources, SSSs, in the Magellanic Clouds, MCs, in order to confirm and study their nature. The 20 ks exposures will allow to determine a precise position, spectral and temporal investigations. Finding new SSS in the MCs is crucial for X-ray source population studies and will provide new information on the physics of individual objects and on the class of SSSs as such. In particular we will address the question if persistent low-luminosity SSSs exist, which is not easily to understand in the framework of stable burning at high accretion rates, or if they are highly variable.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
